After developing an uprated intercooler for the Audi TTRS 8J, our tuning partners approached us to develop a 2nd version that would be specifically designed for those running 500+ BHP. Even for customers with just a stage 1 tune, gains of around 25 BHP can be expected by just swapping out the relatively small and inefficient OEM intercooler (OE Part No. 8J0145804B).

The standard intercooler fitted by Audi has a volumetric capacity of 6.8l, which essentially bottle-necks the inlet tract to the throttle body, creating a restriction when the boost is increased. We utilised our CAD design to ensure that the end tanks flow in the best way possible, spreading the compressed air evenly throughout, this in-turn lead to superior performance over the stock item. We tested several core configurations during development, with the best all-rounder being our bar and plate design. The overall surface area of the intercooler has increased by 30% providing more cooling capabilities. We utilised all the available space with a volumetric capacity of 15.7l, resulting in an overall 130% increase in capacity over the OEM, making this intercooler one of the largest on the market today.

This intercooler is complimented with our modified OEM crash bar (OE Part No. 8J0807109B), that also doubles as the intercooler support.

Why do we test different cores?

When developing an intercooler, we will test several different cores for each application. For example, a bar and plate style core, and a tube and fin style core. Our tube and fin will be tested with different fin pitches and heights, e.g., 22 fins per inch or 17 fins per inch. We will also look at changing the internal fin pitches/shapes and density within the tube, enabling to fine tune the amount of pressure drop the intercooler produces.

Pressure drop is not always a bad thing, as our testing and research has proven on various projects. This is because the pressurized air velocity is being stalled by the pressure drop within the cooler, thus allowing more time to cool the air within the cooler itself, as air passes through the non-pressurized face of the core that is open to the atmosphere. Too much pressure drop
